Title: Apparatus for filtering out solids from a liquid stream
Inventor: ENGELS LOTHAR
IPC: B01D37/03
Filed: 1986-07-24
Abstract: An apparatus is described for filtering out solids from a liquid stream which is particularly simply and inexpensively constructed and in which the filtering does not necessarily have to be interrupted when the solids filtered out are to be removed. For this purpose, a filter element having a closed cross-section is inserted into a vessel from the top, which filter element extends into the interior of the vessel and opens out freely into the bottom part of the vessel at a distance from the vessel base. The inlet for the slurry opens from the top into the filter element, the outlet for the filtered liquid likewise opens from the top into the vessel, more precisely in the intermediate space between the filter element and the wall of the vessel. Furthermore, a drainage orifice for the solids filtered out is provided on the vessel base, the intermediate space between the filter element mouth and the drainage orifice serving as collection space for the solids.

Title: Continuously operating air-jet sieve
Inventor: NIED ROLAND DR ING
IPC: B07B4/08
Filed: 1986-09-20
Abstract: A description is given of a continuously operating air-jet sieve with a planar, rectangular sieve surface and at least one slot nozzle which is arranged underneath the sieve surface and can be moved parallel thereto. In the case of a device of this type, which serves to pneumatically sieve fine-grained materials, air from below is blown through the slot nozzle against the sieve surface whilst the slot nozzle is moved at a small distance from the sieve along the entire sieve surface. Air penetrates through the sieve surface initially in a sharp jet in order to blow through the sieve meshes and to loosen up the material to be sieved and then in a gentle flow in the reverse direction, the fine material being conveyed through the sieve meshes. An air-jet sieve of constructionally simple design which makes full use of the sieve surfaces and makes it possible easily to adjust the retention time of the material being sieved on the sieve - and the resultant high, specific sieving performance - is obtained when the sieve surface is constructed as the floor of a closed vibrating conveyor with a vibrator drive, the mouth of the slot nozzle is of approximately the same length as that of the sieve surface and is directed parallel to its longitudinal side, and the slot nozzle is moved vertically with respect to the conveying direction of the vibrating conveyor.

Title: Planting machine for reforestation
Inventor: CLASS FRITZ
IPC: A01C11/02
Filed: 1986-12-02
Abstract: In conventional reforestation machines, the plants are introduced into the ground via a so-called plant arm which also at the same time has to plough up the soil to be planted. However, this plant arm always has to be set in motion via a hydraulic or mechanical construction. By means of the planting machine for the reforestation of fallow land, pastures and the like, this conventional planting process is not only simplified by the separation of the ploughshare and planting cross, but also improved by the ploughshare constantly being located in the soil, since it can additionally enrich the soil with oxygen.

As a result, a bottle can never burst, which can lead to accidents and hazards. <IMAGE>
Patent DE-3809937-A1 (DE)
Inventor: CAMMENGA HEIKO K
IPC: C04B14/00
Filed: 1988-03-24
Abstract: Fluorescent or phosphorescent pigments based on zinc sulphides, zinc and cadmium sulphides, and alkaline earth sulphides are coated with glass by mixing a finely comminuted glass exempt from heavy metals and having a melting or softening point less than 800 DEG C with the powdered pigment in a ratio of 100:1 to 1:1, preferably 5:1 to 2:1, and then heating the mixture to a temperature at which the glass softens to such an extent that it surrounds the pigment. The mixture can be melted in blocks which are then size reduced to granular form. Mouldings which can be heated to the softening point can also be made from the mixture in paste form. The bodies consisting of pigments coated with glass or having a coating of pigments coated in glass, are embedded in a matrix and then applied as a coating to a substrate. For the manufacture of concrete stones, concrete mouldings or similar, cement and white, pure quartz gravel or quartz sand and/or quartz glass are used as the matrix. For the manufacture of concrete building components, the glass pigment-containing bodies are applied to an adhesive film coated with a retarder which is then placed in the mould. The matrix is then applied and the facing layer so formed is then filled with ordinary concrete. Other suitable matrices are thermosetting plastics, thermoplastics and elastomers. The glass bodies containing pigments can also be melted directly on to a substrate.
